useGSAP dependencies does not work on scrollTrigger 'end' property

[reynaldlamury]

hello, 

 

I've been working on react project, The issue is the 'end' property on scrollTigger does not change when the state changes. How can I solve this ? thankyou

 

here is the code:

  useGSAP(

    () => {

      gsap.registerPlugin(ScrollTrigger);

 

      const tl = gsap.timeline({

        scrollTrigger: {

          trigger: '.daily-wrapper',

          scrub: true,

          start: 'bottom 34%',

          end: 'bottom 5%',

          pin: '.info-text',

          markers: {

            startColor: 'purple',

            endColor: 'green',

            fontSize: '2rem',

          },

        },

      });

 

      tl.to('.info-text', {

        x: -400,

        // y: -50,

        duration: 5,

        onComplete: () => {

          // poinRef.current.style.backgroundColor = 'red';

          console.log('finish');

        },

        // onUpdate: () => {

        //   poinRef.current.style.backgroundColor = 'white';

        // },

      });

 

      gsap.to('.daily-wrapper', {

        scrollTrigger: {

          trigger: '.daily-wrapper',

          scrub: true,

          start: '280px 40%',

          end: `${1700 + sizeChange}px 5%`,

          pin: '.info-text',

          markers: {

            startColor: 'blue',

            endColor: 'orange',

            fontSize: '1rem',

          },

        },

      });

    },

    { dependencies: [sizeChange] }

  );

Without a minimal demo, it's very difficult to troubleshoot; the issue could be caused by CSS, markup, a third party library, a 3rd party script, etc. Would you please provide a very simple CodePen or Stackblitz that illustrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best. See if you can recreate the issue with as few dependancies as possible. Start minimal and then incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen

that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: 

 

Using a framework/library like React, Vue, Next, etc.? 

CodePen isn't always ideal for these tools, so here are some Stackblitz starter templates that you can fork and import the gsap-trial NPM package for using any of the bonus plugins: 

• React (please read this article!)
• Next
• Svelte
• Sveltekit
• Vue
• Nuxt

 

Please share the StackBlitz link directly to the file in question (where you've put the GSAP code) so we don't need to hunt through all the files. 

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions. ✅

Hi,

 

Give the revertOnUpdate flag a try, that should revert the instances inside the hook:

useGSAP(() => {}, {
  dependencies: [sizeChange],
  revertOnUpdate: true, // THIS
});

Hopefully this helps.

Happy Tweening!
